For Summer? |
![Heat Wave logo](images/heatwave2.gif) |
Although rarely recognized, heat is by far the number one killer
of all weather events. Over the last ten years, heat has averaged
nearly 200 fatalities a year, with flash flooding being second to
heat with 90 fatalities a year. In 1995 alone, there were over 1021
heat related fatalities. Extreme heat affects all who live in the
Ark-La-Tex, but the elderly, poor, infants and those who work outside
during the summer are the most likely to succumb to the heat.

Heat Index Chart
Temperature vs. Relative Humidity
How to read the chart: find the temperature on
the left hand side, then move to the right until you find the column
for the approximate relative humidity. That number will be the temperature
that it will "feel" like. Example: A temperature of 95 and relative
humidity of 50% will "feel" like 107 degrees. Add up to 15 degrees
if in the direct sun.
